When the free segment is used up during CP disable, many write or
ioctl operations will get ENOSPC error codes, even if there are
still many blocks available. We can reproduce it in the following
steps:
dd if=/dev/zero of=f2fs.img bs=1M count=55
mkfs.f2fs -f f2fs.img
mount f2fs.img f2fs_dir -o che

This fixes a regression which prevents parallel DIO reads.

There was a problem that did not subtract the super block area when calculating
the usable segments for a single zoned device with a conventional zone.
This resulted in incorrect the overprovision and reserved area.
<256MiB legacy block + zoned block w/ 32MiB zone size>

There was a problem that did not subtract the super block area when calculating
the usable segments for a single zoned device with a conventional zone.
This resulted in incorrect the overprovision and reserved area.
<256MiB legacy block + zoned block w/ 32MiB zone size>
